Oil leak

Greetings all, from Co Clare, Ireland west.My 1986 VT 750 Shadow has been leaking oil. I replaced the gasket on the stator cover,it still leaks. The problem is with the grommet at the bottom-it has shrunk. How/where can I get part, does it have a part #.

Thanks for the replies. I don't recognise the part that I think I need, from the diagrams. What I am calling a "grommet" is at the bottom of the case and is a conduit for connections to the neutral switch.

Aha! Only now I realise why I don't recognise my missing part in the diagrams posted to my appeal. The diagrams shown are of the right hand side/clutch side. My problem is behind the cover on the left. I would appreciate a diagram and parts list for that side.
